Because TSN doesn't give us nearly enough Bob McKenzie thanks to the NHL's new TV deal with both Sportsnet and McKenzie's TSN = a whole hell of a lot of geo-blocking videos, here's 2:35 of McKenzie talking about the NHL's mumps outbreak with NBCSN's Kathryn Tappen (via Pro Hockey Talk's Dhiren Mahibian).

McKenzie explains that Sidney Crosby had already suffered damage to his salivatory gland thanks to a scrap with Riley Nash, so that was the reason that the Penguins allowed him to meet with the media--and he does a superb job of explaining why childhood immunizations aren't 100% effective:

Other good backgrounders: ESPN's Katie Strang and Yahoo Sports' Greg Wyshynski.

My hope is that the NHL's teams, which are finally providing booster shots to players, coaches and team personnel (from a Wings perspective, it was fascinating to hear Mike Babcock's lecture on the subject because he revealed that many European players don't get the mumps-measles-ruebella vaccine) will be fitting the bill for booster shots for the media.

Working with NHL players = understanding that you're going into an environment in which massive amounts of physical activity, sweaty equipment, heavy travel schedules and workloads for everybody and everyone bringing in the germs of any school-age kids to a giant petri dish of handshakes, coughing, spitting, sweating and talking in close proximity...

But the fact that this virus can be passed on while people aren't displaying symptoms + vaccine success rates in the 85% range = there's significant risk for not only the NHL's family, but also the families of the people who cover the team. Prophylactic immunization of all adults interacting regardless of employer makes the most sense here in terms of nipping this damn thing in the bud.
